To all whom it may concern:

Be it known that I, FRANK H. FoLnnN, citizen of the United States,residing at Blair, in the county of Fi ashington and State of Nebraska,have invented certain new and useful Immovements in Multimolding TwoSide Delivery Hand Brick- Machines, of which the following is aspeciiication.

My invention relates to improvements in brick molding machines in whichcomparatively large numbers of concrete bric ZS of a predetermined formand size are molded at one operation; and the objects of my improx'ement are, first, to provide a machine for the rapid and simultaneousmolding of a number of concrete bricks and to facilitate the quickoff-bearing of the finished product to leave the machine at once freefor the succeeding operation; second, to provide in such a machine meansto mold two ornamental faces on each brick or to mold bricks having asunk-panel bottom bed and an ornan'ientally molded regular front edge orface; and, third, to provide an eflicient economically constructedstructure of machine parts and supporting frame to perform otheressential functions hereinafter more fully set forth.

I attain these objects by the mechanism illustrated in the accompanyingdrawing in which- Figure 1 is a perspective view of a whole machine,designed to mold ten bricksfive on each side-at one operation, showingthe molds closed ready to be filled with the concrete; Fig. 2, is aperspective view of the rectangular frame 2121 to strengthen the centerof the machine body, to stop and support opening mold-members at theoutward limit of their movements, and to provide pivot support for theoutwardly-rocking receiving-boards and the off-bearing palletboards andto stop and support them at the outward limit of their movements; Fig.3, is a vertical cross-section, at lar er scale, through the second pairof 'i'nolds from the end, where indicated by the broken line 9 in Fig.1; Fig. l, is a cross-section through the end pair of molds whereindicated by the broken line 6 of Fig. 1, showing an inside elevation ofthe connected leg-head and end of the body of the machine; Fig. 5, is aperspective view of an end half of the castiron bod franie' F10. 6 is aersnective view of a 7 b 1 i I portion of a removable front orlace-plate for molding bricks of various ornamental front edge or face;and, Fig. 7, is a perspective view of the machine showing the moldsopen, and delivering the completed bricks,

' and parts are removed and a central portion cut away to disclose theconstruction and movements of the members.

Throughout the several views curved broken lines indicate the sweep ofrocking or swinging parts.

Similar numerals refer to like members throughout the different views.

The machine as here illustrated is duplex or double-delivery; moldingand throwing out ten completed bricks, five from each of its twolongitudinal sides at one operation.

A central longitudinal bar 4 serves as the vertical partition betweenopposite sides, also as baclsplates 4 to the individual flasks or molds;reinforced by widening at its base i it becomes a central support orback-bone to the body of the machine. From both sides of this thereprojects laterally, crosswebs to form the vertical partitions orendplates 5 between individual molds and the ends 5 and 5 of the wholebody; preferably it is all made integral of a single piece of castmetal.This body is supported at each end by a pair of legs 2 having a head 2with a flange 2 fastened to the insideof the lower edge of the end 5,which extends below the other body members to facilitate such fastening.Integral cross braces 2 span each pair of legs and opposite pairs areconnected by the side pipe-rods 3 threaded at their ends to receive nuts3 on both sides of said legs.

Through the lower outer corners of the partitions 5 and ends 5 arejournaled the longitudinal rock-shafts 9 and 9'. On each end of therock-shaft 9 there is mounted to rock therewith, a quadrant gear 11. Oneach end. of the rock-shaft 9 there is mounted, to rock therewith, agear 10 of like diameter to engage with the gear 11, but of longer areto mesh with a gear-wheel 8 of one-half the diameter, mounted one ateach end of a larger driving rock-shaft 6, journaled below in boXes 6 onthe leg-heads 2 as shown in Figs. 4 and 7. A lever having a weightedhandle-end 7 is rigidly mounted on one end of the driving rock-shaft 6;which weight retains the shafts rocked to the position shown in Fig. 7with the molds open for delivering the bricks; or by throwing the leverover, a one-half revolution, to thefiposition indicated by thebI'OkGIfillIlGS inlFig. 7 and as shown in support the bottom-plates attheir inner or swinging edges when the mold is being filled.

- The outer edge of the bottom-plate projects beyond the outer ends ofthe partitions 5 as shown at 13 in Figs. 3 and 7, equal to the thicknessof the outside or face-plate 17, the lower edge of which face-platerests thereon when the molds are closed for filling;

as indicated by the broken lines in Fig. 7 and by the space between thevertical leg 12 and the outer end of the adjacent partition 5, in

Fig. 3. The outer vertically tilted legs of the L-shaped levers 12 12etc. bear against the outside of said face-plates where they areretained by the bars 18 and 18, in the position shown in Fig. 1 andindicated by the broken lines in Fig. 7.

The bars 18 and 18 are fastened at their ends to the ends of the outerradial arms 11" 11 and 10 10, which are preferably integral parts of thegears 11 and 10, and oscillate therewith. The integral arms 10 and 11are disposed parallel with and spaced from the arms 10 and 11 to form aradially-opening fork on each gear to removably receive and carry theends of said faceplate as shown in Fig. 1 and in Fig. 7. Theseface-plates may have different kinds of ornamental panel-molds as shownat a, b, c and d. They are provided at their ends with the inclined lugs19, 19 etc. which engage the outsides of the'arms 10 and 11 to controlthe face-plates endwise and bring the panelmolds into correctregistration with the brick molds. .The body ends 5 have base extensionsat each end convexly curved to form stationary cams 5 as shown in Figs.4 and 7. These cams act against the lower edges of the face-plates 17,when the molds are opening, to start them out from the base of the forksas shown at 10 in Fig. 3 and in Fig. 7; the resulting position of saidface plate is indicated by broken line sections in Figs. 3, 4 and 7.This movement starts and separates the beds of the bricks from thebottom-plates and their panel-molds, which at this stage of theoperationthe end of the opening movementare standing vertical see Figs.3 and 7.

If plain face-edge bricks are being molded,

the face-plates 17, with the bricks resting face down thereon, may nowserve as pallet piece as shown in Fig. 2.

boards and be withdrawn from the forks, by

grasping their projecting ends, and the bricks thus borne off. But, formolding ornamental-face bricks this would require too many expensiveface plate pallet boards with panehmolds. For which reason and to meetother requirements a number of parts are attached and combined asfollows: A rectangular frame consisting of the longitudinal side-bars 21and 21 connected by end bars 21 and 21, is preferably cast in a singleVertical extensions at each side of the centers of these ends arefastened to the lower edges of the end partitions of the mold-body. Seebolt holes therefor at 2]., 21 etc. The bars 18 and 18 strike on top ofthese ends 21 and 21, which serve as stops to limit the openingmovements of the molds. A pair of rods 22 and 25 are disposedlongitudinally at each side of the machine and their ends fastenedthrough the end-bars 21 and 21 as shown. Near each end of each outer rod22 an L-shaped bar 23 is mounted as shown, to oscillate thereon seeFigs. 1, 3 and 7. The pair of L-shaped bars on each red are connected bythe receiving-board or table 24 fastened on top of the short legs of theL-shaped bars between the ends 21; which board and the ends of the legsto which it is fastened strike on the rod 25 to limit its inward anddownward swing; and the rods are disposed in height to bring the top ofthe receiving-board level with the outer or under side of theface-plate, as indicated in broken-linesection at 17 in Figs. 3 and 7,when the molds are open. From this position the face-plate with themolded bricks thereon may be drawn laterally out of the forks to theposition shown on the receiving-board 24, bringing its top edge and thetop bed of the brick 16 against the vertical pallet board 20. Thispallet board is removably supported in angular relation to saidreceiving-board by the L-shaped bars 23. The whole may now be tiltedoutward to the position indicated by the broken lines 23 in Fig. 7 or asshown below by the faceplate 17, and pallet board 26 with finishedbricks 16 16 thereon; also a like position is shown in cross-section onthe opposite side of the machine at 20 and 16 in Fig. 3.

The outer legs of the L-shaped bars 23, 23 etc. strike on the side-bars21 and 21, as shown in Figs. 3 and 7, to limit the swing and suppert thepallet board 20 horizontally. The back or lower edge of the outwardlytilted pallet board strikes the outer edge of the raised portions of theend-bars 21 and 21, through which the rods 22 and 25 are fastened, andforce it, with the imposed finished bricks, slightly away from themold-face of the face-plate, as shown in broken lines 23 in Fig. 7, at23 in 3 and by the positions of the finished bricks 16, 16 and 16 inthese views. As the pallet board is raised and drawn laterally away tobear off the finished bricks, the face-plate falls away from them to bereplaced in the forks and the molds closed for the next filling.

When the machine is assembled and closed for filling, the outervertically disposed legs of the L-shaped levers 12, 12 etc. are disposedbetween the face or front-plates 17 17 and the bars 18, l8,-see Fig. 7,and Fig. 1, and therefore with the attached bottom-plates 13 must swingwith the rocking of the rockshafts 9 and 9. But when the machine is openand the front-plates removed then each bottom-plate with its attachedLrshaped levers may be swung independently for cleaning or repairs.Driving the rock-shaft gears at both ends of the machine by the smallergear-wheels S mounted at the ends of a heavy longitudinal driving-shaft6, I am enabled to use lighter rock-shafts 9 and 9 without torsionalspringing, have a greater purchase to operate the molds and bring theweighted lever into the most effectual position to re tain the moldsopen or closed and being central, most out of the way during other partsof the operation of molding and delivering. Difierent shapes and smallersizes of bricks can be molded by attaching counterparts of the desiredforms to either the bottom-plates or face-plates as required,
